The psychiatric definition of narcissism seems to be confused with egomania, which is quite a different thing. Freud has an essay on narcissism which is very interesting, and consistent with the idea of the Greek myth. The narcissist is self-involved, and does not seek the approval of others. Freud notes that the narcissist can be attractive to others, like a tiger or a beautiful woman, precisely because of this air of self-satisfaction.
